“…The 2D/3D Vertical Seismic Profiling (VSP) data can provide a high‐quality seismic image with significantly higher resolution than surface seismic data (Planchart et al 2007; Lou, Cheng and Doherty 2009; Muller et al 2010). However, VSP data have a major limitation in that they only image a relatively narrow area around a borehole.…”

A B S T R A C TWe have developed a straightforward and ray based methodology to estimate both the maximum offset and reflection imaging radius for multi-layered velocity models, which can be used for a 2D/3D VSP survey design. Through numerical examples, we demonstrate that the presence of a high-velocity layer above a target zone significantly reduces the maximum offset and reflection imaging radius. Our numerical examples also show that including in a migration VSP data acquired beyond a recommended maximum offset, radically degrades the quality of the final VSP image. In addition, unlike the conventional straight-line based approximation that often produces an incorrect large reflection imaging radius, our methodology predicts the VSP imaging radius with more accuracy than does the conventional approximation.
